  • MI-1271 Measurement Microphone / MI-3170 Microphone Preamplifier
    MI-1271 Measurement Microphone / MI-3170 Microphone Preamplifier

We are pleased to announce the release of a new free-field 1/2-inch electret condenser microphone and preamplifier compliant with IEC 61094-4:1995 Type WS2F.
By employing a titanium diaphragm and improving electret performance, a wide temperature range of -30°C to +80°C has been achieved.

Furthermore, it supports a wide frequency range of 1 Hz to 20 kHz and achieves reduced self-noise. Because the preamplifier is a CCLD (constant current drive) type, it can be used with equipment equipped with a CCLD power supply by connecting a BNC cable without using an intermediate microphone amplifier.

 

Main uses

Sound measurement near the engine
Measurement on a temperature-sensitive engine bench
Cold start test, cold weather test
Measurement of low-frequency sound, etc.
